The invention relates to the technical field of tire manufacturing, in particular to a tread rubber composition of a tire with ultralow rolling resistance, a mixing method and application of the tread rubber composition in wheel preparation. The invention relates to a tread rubber composition of a tire with ultralow rolling resistance. The tread rubber composition is prepared by mixing the following raw materials based on 100 parts by weight of raw rubber components: 100 parts of raw rubber, 50.0-70.0 parts of white carbon black, 8.0-25.0 parts of silica fume and 1.0-10.0 parts of carbon black, and a proper amount of an anti-aging agent, an active agent, a silane coupling agent and a vulcanizing agent. The BET specific surface area of the white carbon black is 120-200m < 2 >/g, and the BET specific surface area of the silica fume is 15-25m < 2 >/g. According to the composition, the white carbon black and the silica fume are used as fillers, so that the processing performance of the rubber material can be improved, and the key indexes of the rubber material related to the tire rolling resistance are obviously improved.
本发明涉及轮胎制造技术领域,尤其涉及一种超低滚动阻力轮胎的胎面橡胶组合物、混炼方法和在轮制备中的应用。一种超低滚动阻力轮胎的胎面橡胶组合物,该橡胶组合物按生胶组分为100重量份由包括以下组分的原料混炼制备得到:生胶100份,白炭黑50.0‑70.0份,微硅粉8.0‑25.0份,炭黑1.0‑10.0份;以及适量的防老剂、活性剂、硅烷偶联剂和硫化剂;所述的白炭黑BET比表面积为120‑200m2/g,微硅粉的BET比表面积为15‑25m2/g。该组合物通过并用白炭黑和微硅粉作为填料,可改善胶料加工性能,且与轮胎滚动阻力关联的胶料关键指标有明显改善。
